The invention vis illustrated .in the accompanyjing drawing, wherein- Figure 1 is a perspective View of the sturm-17 2 away, -parts Ein -cross -'section iandparts in enlarged detail.

Figure 26 is "a cross Asectional eleva-tion fof an improved screen 'sash which may be used vvas lan initerchangeable lunit with the glass panes .of the storm Lwindew.

By lreferring 'to the drawings and Figures `-1, 2 and B in particular it -will be seen lthat `a Astorm `window Ahas been mounted Aupon an exterior window casing -I|J which includes asill .or ledge and 'that the `irarneporltion of the storm window comprises `a lchanneled shape 4incorporati-ng double channels, one of which -forms the inner fedge ci Athe Trame portion-of the storm window andthe other Af "which l'fiorms the outer edge, the linner 'channel being lindicated by the numeral I2 and the outer channel by the numeral I3. The exterior HI ofthe channeled shapeforms an'outer Afacing Y'and the inner `side 45 of 'the ychanneled "shape fornrsan inner facing, vthe facngs I4 `and I5 being spaced apart by vvmeans fof a web 'IB the length of which determines fthe width of the 'channels I2 and I3. '-Ihe 'channel i12 being the Vone forming 'the inner edge of the frame is adapted to receive a pair of glass panes |"I land IB, each "of whichispreferably of triple strength `plate glass. It willthus vbe seen that 1when sec-- `tions of :the 'cl'ranneled frame are cut in suitable Elengths and fitted to one vanother with diagonal joints, a rectangular frame is formed with continuous inturned anges defining the channel 'I2 ltherebetween. This frame Xmaybe united at Athe lcorners by suitable L-shaped brackets as illustrated in'Figure 4 which are 4press iit 'in vposition 'together with la lsuitable cement or bolted. or riveted therein, as desired. The frame `may be assembled lon A"alle 'vvindow casing IO -as illus- 'trated in Figure =1. In either'event in order Vthat double'g'lass panesmaybe positioned therein, por- "tions of `the -in-'turne'd ange kof the inner facing A:I''are cutaway at veach'side to provide'clearance ior 'positioningthe Vglass panes Ii `and yI8 lin the channel I2. By referring to Figures 1, 2 and A5-of the drawings, it will-be observed'thatthe'inturned *flange Of 'the facing I5 is not cut away near the =upper and 4lower sections lof `the frame and these 'remaining porti'onsare indicatedby -the Inumerals 15A. Thecutiawayarea-of zthe facing I5, as is kbest J'illustrated in Figure 55, is sufficient to en =able leither-'oneof the glasspanes Il and lI-8 to 'be -`positioned lin the channel il2. "-I-he strip so removed from each side ofthe frame -isutilized for fm'e'difying the channel lI2 lirorn double glass to single glass iwidth -across theftop and fbottom 'ci -the :framesand :snchadde'dfstrips i are indicated by frame.

the numerals I9 and ISA, respectively. It will be observed that the added strip I9 is positioned in the top channel I2 adjacent the inner facing I5 and that the added strip IBA is positioned in the channel I2 adjacent the exterior facing I4. This formation provides for fthe location of the upper and lower glass panes, the upper pane being indicated by the numeral I8 and the lower pane by the numeral Il, the upper pane being positioned adjacent the exterior facing I4 in the upper half of the frame and the lower pane being positioned adjacent the inner facing I5 in the lower half of the frame. In order that the upper pane may be retained in the position illustrated, additional filler strips 20 are employed, which ller strips 20 are positioned vertically in the channel I2, one at each side of the frame, and they are of a length so `that their uppermost ends lie immediately under the bottom of the uppermost pane I8 thereby providing ledges upon which it may rest. It will thus be seen that when a storm window frame is formed from four pieces of the channeled frame material and assembled in the manner illustrated and described and modified by I4 and moved upwardly until the uppermost edge thereof registers with the single channel It?. formed in the top of the frame. When in such position its lowermost edge is moved outwardly so that the sides of the pane I8 continuously engage the in-turned flanges of the exterior facing I4 and the bottom of the pane I8 rests upon the upper ends of the added strips 2D. The upper pane I8 will remain in this position. The lower pane is then positioned in the frame flush against the inner surface of the upper pane and so that its sides lie within the channel I2. In this position it may be lowered until its bottom-most edge registers with the single channel in the The vglass pane in this position forms a, workable yweather tight closure, and to insure against the possibility of movement, rattling or accidental displacement a pair of spring tensioned hinged brackets 2l are provided one on each side of the frame and they may be mounted directly on the frame material itself or on the casing Il) of the window on which the storm window is positioned. In either-event, they are so formed that they may be swung about into contact with the uppermost edge of the inner, lower pane Il where they will remain under spring tension holding the uppermost edge of the lower pane I 'I' against the lowermost edge of the upper pane I8.

By referring to Figure 5 of the drawings, the spring tensioned brackets 2| may be seen to comprise spring tensioned mountings 22 in which the actual brackets 2| are `pivotally positioned and sprung in relation thereto preferably by a separate spring incorporated therewith. In Figure 5 of the drawings a knob 23 is shown affixed in a drilled opening in the lowermost sash 2l to provide a convenient hand hold.

For summer use the upper `or the lower plate glass pane may be removed and a screen insert of comparable size and thickness may be sub- 4 stituted. Such a screen insert is illustrated in Figure 6 of the drawings wherein a pair of plastic frames 24 and 25 having a section of plastic screen 26 positioned therebetween in a sandwichlike manner have been united through the use of suitable cement and/or heat so as to form a rigid unitary structure, the total thickness of the screen sash section being equal to the thickness of the glass pane it is adapted to be interchanged with.

By referring to Figures 2, 3 and 4 of the drawings it will be seen that a corner bracket 21 illustrated in Figure 4 in enlarged detail may be employed as heretofore referred to in the assembly of the frame of the invention. The corner bracket 21 is shown in position in the cross sectional elevations of Figures 2 and 3 wherein it is indicated by the numeral 2l and it will be observed that it has been press fit in the corner sections of the frame being positioned in the exterior channel I3. In this position where it may be located by cementing, heat treatment or by bolting or riveting, depending upon the material of the frame and the bracket, the brackets, in conjunction with the frame structure cooperate to form a unitary window frame.

It will thus be seen that in forming the storm window of the invention certain advantages over storm windows heretofore known in the art are realized. Among these are the formation of the frame portion of the storm window of a simple channeled shape'which may be and preferably is of extruded plastic while the sash portions themselves are simply unframed sections of plate glass or clear plastic material. The storm window due to the unique construction need not employ weather stripping of any nature or complicate means for positioning and holding separately framed window panes as has heretofore been customary in the art as the formation of the simple' frame cooperates with the glass or plastic panes forming a weathertight closure. The storm window may be installed upon the exterior or the interior of a conventional window and forms a neat, unobtrusive, highly ecient weather closure in either position. When positioned on the exterior of a window casing as shown in Figure l, an added wooden back-up member is preferably employed across the bottom portion of the frame to provide a structural portion of the window frame against which the storm window frame may be located. The window frame may -be ush t with the casing IB of the window upon which it is in Stalled by the simple expedient of trimming oif the portion of the exterior facing I4 which extends beyond the interior facing I5, thus permitting the whole frame to be positioned against the inner structure of the window casing and pro- Viding a neater assembly as no exterior flange remains. In such position the frame is positioned by screws driven through the web I8 into the casing or in the manner shown in Figure 4, the screws being driven into the inner structure of the conventional window frame.

Having thus described my invention. what I claim is:

1. In a storm window a frame comprising a channeled shape the channel in said shape being of a width sufficient to receive therein two thicknesses of transparent material as panes, means in said channel for positioning one of the panes in upper outer position in the said channel and for positioning the other one of the said panes in irmer lower position in the said channel, the said panes partially overlapping and touching one another, vertical sections of the said channeled shape being cut away to permit the said panes to be moved into and out of the said channel.

2. In a storm window a frame comprising a channeled shape the channel in said shape being of a width sufcient to receive therein two thicknesses of transparent material as panes, means in said channel for positioning one of the panes in upper outer position in the said channel and for positioning the other one of the said panes in inner lower position in the said channel, the said panes partially overlapping and touchingl one another, vertical sections of the said channeled shape being cut away to permit the said panes to be moved into and out of the said channel, a lip on said channeled shape oppositely disposed from said channel, said lip adapted to overlie a window casing and serve as a means of mounting said storm window.

3. In a storm window a frame comprising a channeled shape the channel in said shape being of a width suiiicient to receive therein two thicknesses of transparent material as panes, means in said channel for positioning one of the panes in upper outer position in the said channel and for positioning the other one of the said panes in inner lower position in the said channel, the said panes partially overlapping and touching one another, vertical sections of the said channeled shape being cut away to permit the said panes to be moved into and out of the said channel, a lip CII on said channeled shape oppositely disposed from said channel, said lip adapted to overlie a window casing and serve as a means of mounting said storm window, tensioning members positioned on said channeled shape and engageable with both upper outer and lower inner panes for holding the same in their respective positions.
